A commemorative service will be held in France to remember those who fought and died at the Battle of Amiens 100 years ago, including 2000 Australians.
The Allies launched the largest attack of the First World War east of the French town on August 8, winning an unprecedented victory on the Western Front.
The battle, which claimed almost 9000 Allied troops, was the opening act of the 100 days which ultimately ended the war, with Australian soldiers in a leading role.
"The victory at Amiens was greater than any other British success of the First World War, and is not only significant for Australians, but for the world, and the service and sacrifice of these soldiers should never be forgotten," Minister for Veterans' Affairs Darren Chester said ahead of the service in France on Wednesday local time.
The attack was so overwhelming Erich Ludendorff, the German Chief of Staff, described it as a black day for the German army.
During this phase of the war, the Australians fought in a series of battles, most famously at Mont St Quentin and Peronne before fighting their last infantry battle on the Western Front at Montbrehain on 5 October 1918.
"As the Anzac Centenary 2014-18 comes to a close it is important to remember these critical battles at the end of the First World War," Mr Chester said.
